By lifting 2D video controls into explicit 3D space, you can resolve ambiguities in object motion and create videos where camera and object movements are geometrically consistent—a major improvement over 2D trajectory-based video control.
GenCine enables artists to control video generation by editing 3D camera paths and object motions in a scene scaffold, rather than using ambiguous 2D trajectories. The system projects these 3D controls into guidance maps that a pretrained video model learns to follow, producing videos with consistent camera-relative motion and improved geometric coherence.
